.NET 2.0 introduces a new class in the System.Web.UI.Design namespace: WebFormsRootDesigner (documentation). Unfortunately, the class only seems to be a stub that, most important, doesn't implement the GetView method (documentation).

If you have a clue where to find a functional implementation please let us know. Drop me a line (you can find the email address here) or add a comment to this entry. Your help is highly appreciated.
